Application ledJuly 24, 1902. Serial No. 116,796.- (No-Inudel.)

I To all whom it may concern:

. oil-burner of .this character which is simple Be it known that I, WILLLAM D. DAWSON, a citizenof the United States, residing at Mangum, in thecounty of Greer,Territory of Oklahoma, have invented certain new and useful improvements in Oil-Burners; and I do declaro the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates-to a crude-oil burner designed for use in connection with stoves,

furnaces, te., for cooking -and heating p urposes; The object of the invention is to provide an of construction, efficientl in use, and comparatively inexpensive'of production and which automatically controls the feed of theoil a required for consumption.

. With theseandother objects in view th invention consists incertain novel features of construction, combination, and arrangei my invention.

`tion showing the adjustable fastening for one ment vof parts, which will be hereinafter more fullyset forth, and'particularly defined in the appended claims.

In the accompanying drawings, Figure 1 is `a top plan view of an oil-burner embodying Fig. 2 is a vertical longitudifnal section of the same. Fig. '3 is a detail secof the supporting platesections, and Fig. 4 is a detail view of the means for'adj usting the air-pipe.

Referring now more particularly to the drawings, the numeral 1 represents au airtight tank provided with an opening 2, closed by a cap or cover3, adapted to close the opening air-tight.' Located belowthis tank is a burnerbowlr, which is in communication through ports 6 with a channel 7, which comupwardly-inclined portion 1l', adapted to have a slight yielding action in a vertical plane and provided at its free end with an e1 bow 12, connected with a short pipe-section 13, which extends downward into the cup 9, so .as to be closed or sealed by the oil rising .in said cup to a point above its normal level.

This pipe-section 13 may be adjusted vertically to regulate its position in the cup 9 to adapt it to be sealed or closed at diderent' levels of the oil by means of a block 11i, slide,

ing on the oil-supply pipe 8 and engaging the inclined portion 11 of the air-pipe 10, said block being formed with a screw-threaded ap` erture to receive the threaded end of an adjnsting screw or shaft 15, journaled in the may be varied or regulated `without in any,

manner varying the position of the ta'nk, thus enabling the air-pipe to be made of any length and the tank to be located at such'a remote distance from the stove that an explosion of 'its contents from the heat of the stove cannot possibly occur.

A'frusto-conical burner-drum 16 yis fitted@ at its lewer'or reduced end in the bowl 5 and is formed at its upper end with a flange 17 to restupon the upper surface of a supportingplate 18, which latter is provided with an opening 19, through which the drum extends. This plate 18 is adapted to be suitably supported' in the nre-box of a stove or furnace and is adjustable to suit different sizes of fireboxes.' To this end it is provided at its corners with slots 20, extending toward the center of the platey and receiving the bolts 21 upon adj ustablc sections 22 to fasten the latter to the plate18. The adjustable sections 22 are of L form and coperateto provideV a rectangular oguter supporting-frame, which iucloses the central portion ofthe plate 18 and whose ends are arranged to overlap, thus allowing saidl sections to be adjusted toward and from the center of the plate to decrease or increase the size of the latter and t fire-boxes of dierent sizes. By loosening up the said bolts 21 thev sections 22 may be moved inward or outward and then clamped in adjusted position by tightening the nuts of said bolts, which exert a clamping pressure to hold the screw securely fastened to the plate 18. The oil-supply pipe 8 may be provided with one or more valves 23 to control the flow of oil to the burner-bowl 5. hIt4 will be understood, of course, that while I have shown in the present instance a single burner connected to the pipe 8 any desired number may be employed, as circumstances may require, to suit the size of the fire-box and furnish any required degree of heat.

In the operation of the burner the valve 23 is opened to allow oil to flow into the pipe 8, whence it passes into the channel 7 and thence through the feed-ports 6 intothe bowl 5 and cup 9.

When the oil reaches the desired level, that contained in the bowl 5 is ignited, and the llames and products of combustion rising therefrom pass upward into the burner-drum 16, through the perforations of which currents of air are drawn which intermix with the smoke and products of combustion and oxygenate the same, thus causing perfect combustion after the manner of a Bunsen burner, producing an intense heat in the nre-box ofthe stove and eecting practically the entire consumption of all the combustible elements of the oil. Should from any possible cause the supply of oil to the bowl 5 and cup 9 be greater than the amount which is being consumed, 4the rising of the oil above its normal level in the cup 9 will close or seal the end of the pipe 13, thus preventing'entrance of air to the tank 1 through the pipe 10, and therebyv cutting olf the llow of oil to the pipe 8. By this means the supply of oil to the burner isautomatically con# trolled and in the operation of the burner is prevented from feeding faster than it is being consumed in the bowl 5 and drum 16, thus obviating all liability of explosions or accidents from an excess feed of oil. This result, it will be understood, is attained by employing an air-tight tank, to which air is introduced to compensate for the outflow of oil .through the `pipe 10, and arranging the open end of said pipe formed by the section 13 so as to `be sealed by the oil when the lat'- ter rises above its normal level.

From the foregoing description, taken in connection with the accompanyingdrawings, the construction and mode of operation of the invention will be readily understood, and it will lbe seen that by the construction of the vparts as shown and described a simple and eective form of burner is provided, and that after the burner has been preliminarily started it-requires little or no attention, as thesupply of oil to the burner-bowl is automatically governed and under no condition can be fed thereto in a greater quantity than that being consumed. In filling the tank it will be understood that the valve 23 is prethe tank to control the ow of air'therefrom to the oil-supply pipe, and means for varying the level at which the inlet of air is cut o without varying the position of the tank,sub stantially as set forth.
